This is an EG toolbox from Matsushita Electric Works. A relative who was an electrician used it for work. The material is likely iron or tin. It's a very heavy toolbox. Since Matsushita Electric Works no longer exists, I think it's a rare item. The company name on the box is embossed, not a sticker. The back has some rust, but it's relatively clean. It also locks with a key. The lid opens on both sides upwards. Size: Approximately 41cm wide, 28cm deep, 7.5cm high (usable space), 14cm including the handle. #Showa #Retro #MatsushitaElectricWorks #National #Toolbox
